CORNELIUS HAYES, OF OSXVEGO, NEV YORK.

GRAIN-ELEVATOR.

.QPECIPICA'IION forming part of Letters Patent No. 317,353, dated May 5,1885.

Application filed March 28, 1885.

To all whom it may concern:

Be it known that I, CORNELIUS HAYES, of Oswego, in the county of Oswego,in the State of New York, have invented new and useful Improvements inGrain-Elevators, of which the following, taken in connection with theaccompanylng drawings, is a full, clear, and exact description.

This invention relates to improvements in that class of elevators whichare used for removing grain, ground land-plaster, and other granular orground substances from the hold of a vessel, or from the lower part of astorehouse to the upper part of the latter. In the operation of theseelevators, the men who work around the foot of the elevator aresubjected to great inconvenience and injurious effects incident to theinhaling of the dust caused by the agitation of the substance in feedingthe same to the foot of the elevator.

It is to overcome the aforesaid difficulties, and also to facilitate theoperation of feeding the substance to the foot of the elevator, which myinvention has for its object; and to that end my invention consists inthe novel construction and combination of parts, as hereinafter fullydescribed, and specifically set forth in the claims.

In the annexed drawings, Figure l is an clevation of an elevatorprovided with my improvements. Fig. 2 is a transverse section on line asm, Fig. 1. Fig. 3 is an enlarged detached perspective View of thecoupling of the ventiduct and its extension, and Fig. 4 is a side elevation of the same.

Similar letters of reference indicate corresponding parts.

A and A represent the so-called elevatorlegs, in which theelevator-buckets travel in the usual and well-known manner, saidelevator-legs being here represented introduced into the hold of a boat,the upper end of the elevator projecting above the boat, and having itsdischarge-spout .9 extended into a building, as indicated by dottedlines in Fig. 1 of the drawings.

l designates a ventiduct consisting of a pipe, which, for protectionfrom injury, is arranged between the elevator-legs A A, and extendedlengthwise thereof. The lower end of the ventiduct is secured to the legA by clips or bands (No model.)

a, and terminates with a flaring receiving month, an, near the foot ofthe elevator-legs, and the discharge end of the ventiduct is extendedtoward the top of the elevator, where it is attached to an iron plate,I), which is bolted onto the top of a wooden plate, a, se cured betweenthe elevator-legs A A, the plate I) being provided with an openingcorresponding to the interior of the ventiduct, and having around saidopening a collar, 0, into which the end of the ventiduct P is inserted.The top of the plate b is provided with guides (l d, between whichslides a plate, 6, and this plate is provided with an opening and acollar, 6, around said opening, similar to that of the plate I).

To the collar 6 is attached a hose or other flexible pipe-extension, P,and the latter 1s connected with the induction-port of an exhaust-fan,F, which, when in motion, serves to draw the dust from around the footof the elevator into the mouth m of the ventiduct P, and through saidduct and its extension 1?, and expel the dust through the discharge-pipeR of the fan, as indicated by arrows in Fig. 1 of the drawings. Thissuction through the ventiduct not only carries away the dust, but alsocreates a circulation of air from the exterior of the boat to the holdthereof, and thus effectually relieves the laborers in the boat of thesuffocating effect which they have hitherto been subjected to.

The coupling and uncoupling of the pipes 1? P is readily effected bysliding the plate 0 onto and off from the plate b. This simple andconvenient coupling of the two pipes is essential, inasmuch as theelevator has to be lowered into and raised out of the boat.

In order to facilitate the operation of feeding to the foot of theelevator the substance to be elevated, I provide the foot of theelevator with side openings, 0, and extend from said openings troughs BB, placed in an inclined position, as shown in Fig. 1 of the drawings.By throwing the grain or other substance into the trough, said substancemoves by its gravity to the foot of the elevator, thus saving the laborof shoveling the aforesaid substance the distance over which the troughsare extended, and also producing less dust in transferring thesubstance.

7 Having described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with the elevator-legs A A, of a ventiduct extendedfrom the foot of said elevator to the upper part thereof and a hose orpipe-extension detachably connected with the upper end of the ventiduct,as and for the purpose specified.

2. In combination with the elevator-legs A A, the pipe P, securedbetween said legs, and having its receiving end near the foot of thesame, and its discharge end extending toward the top of the elevator, ahose or pipe extension detachably connected with the pipe P at the upperpart of the elevator, and an exhaustfan connected with saidpipe-extension, substantially as and for the purpose set forth.

3. In combination with the elevator-legs A A, the pipe P, arrangedbetween said legs and having its receiving-mouth near the foot of thesame, the plate a, secured between the elevator-legs near the upper endthereof, a pipe-coupling on said plate, having the upper end of the pipeP connectcd'with it, a hose or pipe extension connected with saidcoupling, and an exhaust-fan connected with the pipeextension,substantially as described and shown.

4. In combination with the elevator-legs A A, the pipe P, arrangedbetween said legs and having its receiving-mouth near the foot of thesame, the plate a, secured between the elevator-legs near the upper endthereof, the plate b,.attached to plate a, and having an open ingwith acollar, c,'connected to the upper end of pipe P, guides (Z d on theplate I), the

plate 0, sliding between said guides and pro- Vided with an opening, anda collar, 0, around said opening, and the pipe-extension P, connectedwith the collar 0, substantially as described and shown.

5. The combination, with the elevator-legs A A, of the troughs B B,extended from the foot of the elevator, substantially as and for thepurpose set forth.

6. The combination, with the elevator-legs A A, of the ventiduct P,having its receivingmouth at or near the foot of the elevator, and itsdischarge end extending toward the top of the elevator, and the troughsB B, extending from the foot of the elevator, substantially as describedand shown, for the purpose set forth.

In testimony whereof I have hereunto signed my name and affixed my seal,in the presence of two attesting witnesses, at Syracuse, in the countyof Onondaga, in the State of New York, this 12th day of March, 1885.
